Definitions

  • the invention relates to a contactlessly operated sanitary fitting with a water outlet connected to a water outlet, a mixing valve inserted therein and a shut-off valve which can be controlled by a proximity sensor and which can be actuated by means of a control device as a function of the control signals of the sensor Supply of the control unit with electrical energy, a turbine inserted into the water line and an associated generator, preferably connected to an energy store, are provided.
  • a sanitary fitting of this type is known from DE-C1- 39 05 759.
  • the water pipe is designed as an annular channel into which the blades protrude into the turbine.
  • the generator, the shaft carrying the blades of the turbine and a transmission gear are arranged in a separate housing.
  • the object of the invention is therefore to design a contactlessly operated sanitary fitting of the type mentioned in such a way that the electrical energy emitted by the generator can be fed directly to the control unit or the energy store without problems and almost without loss and that no special seals of the generator or other components are to be made.
  • the generator can work at high speed without the need for a lossy transmission gear, so that a good utilization of the flow energy of the water and therefore a high efficiency is given.
  • the manufacturing effort required for this should be kept low, and the parts to be inserted into the water pipe should also be simple in their structural design and small in size, thus ensuring trouble-free and maintenance-free operation over a long period of time is guaranteed and the sanitary fitting can be used almost without restriction and can also be retrofitted.
  • this is achieved in a sanitary fitting of the aforementioned type in that the impeller of the turbine is mounted so as to be drivable directly in the water duct of the water pipe about an axis extending in the direction of flow and is equipped in the outer region with a plurality of permanent magnets arranged uniformly distributed over the circumference , and that in the wall of the water pipe or on this at the level of the permanent magnets two or more magnetic coils aligned in its axial direction are used, which form the generator in cooperation with the permanent magnets arranged in the impeller of the turbine.
  • the water pipe with a first and a second flow-through intermediate wall, between which the impeller of the turbine is arranged and which is rotatably supported in the intermediate walls by means of centering tips and centering holes.
  • the first intermediate wall upstream of the impeller of the turbine should have one or more nozzle openings incorporated into the outer region thereof and preferably arranged inclined in the direction of flow, and the impeller with the diameter region of the nozzle openings of the first intermediate wall arranged preferably axially perpendicular to these inclined guide vanes, the number of guide vanes of the impeller should correspond to the number of nozzle openings machined into the first intermediate wall.
  • the impeller of the turbine can be provided with guide vanes arranged radially inside the permanent magnets and capable of being acted upon by the flowing medium.
  • the two intermediate walls on the outer sides and / or the impeller of the turbine on the side facing away from the first intermediate wall can have conically shaped, aerodynamically shaped extension pieces.
  • the two partition walls and the turbine impeller inserted between them can be expediently arranged in a conical extension formed in the water pipe.
  • the energy store can be formed by a capacitor.
  • a sanitary fitting is designed according to the invention, there is not only a compact structural unit which can be used almost anywhere and also retrospectively and which enables trouble-free operation without connection to a power network, but the electrical energy can also be easily and without major losses from the Generator are transferred to the control unit or the energy store. Sliding contacts are not required for this, nor are there any electrical cables to be arranged in the water line, the coils inserted into them are rather stationary and can be electrically connected to the control unit or the energy store without any problems. And there the shovels of the Turbine impeller when water is withdrawn from the nozzle openings and thus flows at high speed, high speeds can also be achieved. A sufficient amount of energy is therefore always available to operate the sanitary fitting. Despite the low construction costs, a high degree of utilization of the energy contained in the water is provided and trouble-free and maintenance-free operation is ensured over a long period of time without batteries having to be replaced and disposed of.
  • the sanitary fitting 1 shown in FIG. 1 has a mixing valve 6 and a shut-off valve 8 connected downstream thereof, which can be controlled by means of a sensor 10. That from a cold water pipe 2 and a hot water pipe 3 via branch pipes 4 and 5 to the mixing valve 6 supplied water is mixed in this in accordance with the set water distribution and can flow out of a water outlet 9, to which the mixed water is supplied via a water pipe 7, as soon as the shut-off valve 8 is opened as a function of a pulse emitted by the sensor 10.
  • a control unit 11 which is connected via a signal line 12 to the sensor 10 and a further signal line 13 to the shut-off valve 8, serves to excite the shut-off valve 8 equipped with an armature winding as a function of the pulses from the sensor 10.
  • an energy store 14 designed as a rechargeable accumulator or as a capacitor is connected to the control unit 11 to supply it with electrical energy and to supply the armature winding of the shut-off valve 8 via a line 15. Operation without the energy store 14 is also possible.
  • the water supply to the water outlet 9 is thus controlled and, according to the setting of the mixing valve 6, mixed water from cold and warm water is supplied as soon as the control device 11 is activated by the sensor 10.
  • a generator 31 is assigned to it, which is connected to the energy store 14 via a power line 34.
  • the generator 31 is in drive connection with a turbine 21, which can be driven in rotation about an axis A extending in the flow direction by the water flowing in the water line 7.
  • the turbine 21 and the generator 31 are, as can be seen in particular in FIG. 2, installed in a pipe section 16 designed as a connection piece, which has a conical extension 18 for this purpose and by means of Thread 17 is easy to insert in a line.
  • the pipe section 16 is equipped with a first intermediate wall 23 and a second intermediate wall 24, between which the impeller 22 is mounted between tips.
  • an insert 41 is inserted into the impeller 22, which is provided on one side with a centering tip 42 and on the other side with a centering hole 43 into which a centering tip 44 attached to the first intermediate wall 23 engages.
  • the centering tip 42 of the insert 41 engages in a centering bore 46 of an insert 45 which is inserted into the second intermediate wall 24 which is provided with flow channels 24 ⁇ and can therefore be flowed through.
  • a plurality of nozzle openings 25 are also incorporated into the first intermediate wall 23 in the outer diameter range, and the impeller 22 of the turbine 21 is equipped with these associated guide vanes 26, which are thus acted upon by the water emerging from the nozzle openings 25 at high speed when water is withdrawn. so that the impeller 22 of the turbine 21 rotates at high speed.
  • the first intermediate wall 23 is provided on the flow side with an aerodynamically shaped extension piece 29, through which an annular channel 19 is thus formed, via which the water is supplied to the nozzle openings 25. And since the impeller 22 of the turbine 21 also has an attachment piece 30 projecting in the direction of the second intermediate wall 23, it is ensured that the flow losses in the region of the turbine 21 and the generator 31 are kept low.
  • the turbine 21 ' is arranged radially within the generator 31'.
  • the rotor 22 'equipped with guide vanes 22' of the turbine 21 'between two on the intermediate walls 23' and 24 'attached centering tips 42' and 44 ' is rotatably supported and carries on the outer circumference the permanent magnets 32' of the generator 31 ', the with rotation of the impeller 22 'interact with the magnetic coils 33' inserted into the wall 16 'of the pipe section 16', so that in turn electrical power is induced in them, which can be fed via the power line 34 to the energy store 14 or directly to the control unit 11.
